Omaha, Neb., January 30, 2007 
Union Pacific Corporation (NYSE:UNP) announced that its Board of Directors voted today to authorize the repurchase of up to 20 million common shares by year-end 2009. The Board also increased the quarterly dividend on the company’s common stock by 17 percent to 35 cents per share. The increased dividend is payable April 2, 2007 to stockholders of record February 28, 2007.

"Last week, Union Pacific reported its best year ever, achieving all time records for operating revenue, operating income and net income," said Jim Young, President and Chief Executive Officer. "Looking ahead, we believe our future earnings and cash from operations will be sufficient to invest in growth opportunities, maintain our balance sheet and provide cash to further enhance shareholder value. We are committed to enhancing shareholder value as we continue to improve the overall returns on our business."

The new 20 million common share repurchase program calls for repurchasing roughly 7 percent of Union Pacific’s approximately 270 million publicly held shares over the next 3 years. Timing and volume of share repurchases will be at the discretion of management. Any share repurchase under this program may be made in the open market, or otherwise.

Union Pacific has paid dividends on its common stock for 108 consecutive years.
